Class RandomBoundaryConstraint

java.lang.Object
  net.sourceforge.cilib.problem.boundaryconstraint.RandomBoundaryConstraint

All Implemented Interfaces:

Serializable, BoundaryConstraint, Cloneable

public class RandomBoundaryConstraint
extends Object
implements BoundaryConstraint

If a particle oversteps the boundary it gets randomly re-initialised within the boundary and its velocity gets updated.

Method Detail

getClone

public BoundaryConstraint getClone()

Create a cloned copy of the current object and return it. In general the created copy will be a deep copy of the provided instance. As a result this operation an be quite expensive if used incorrectly.

Specified by:

getClone in interface BoundaryConstraint

Specified by:

getClone in interface Cloneable

Returns:

An exact clone of the current object instance.

Object.clone()

enforce

public void enforce(Entity entity)

Enforce the defined boundary constraint on the provided Entity.

Specified by:

enforce in interface BoundaryConstraint

Parameters:

entity - The Entity with which the boundary is to be enforced.
